Design of an Intelligent Water-Rescue Life Jacket System Based on Satellite Positioning

In response to safety hazards faced by maritime enthusiasts and workers, and in order to reduce the occurrence of maritime accidents, this paper presents the design of an intelligent waterborne life jacket system based on satellite positioning. A multifunctional smart life jacket for maritime rescue is designed in this paper. This novel life jacket consists primarily of two components: the client-side (life jacket) and the mobile phone-side. In the complex external environment of the deep sea, once the client-side life jacket is activated, it can promptly send location signals via a GPS communication module. The server-side where rescue personnel are located receives the distress signal and transmits the rescuer's location information to the rescuer's mobile terminal through an app. The mobile terminal then uses its satellite navigation positioning system to pinpoint the location, enabling rescuers to quickly locate the stranded individual along the navigation route. Experimental test results demonstrate that the system, through embedded devices, can accurately monitor the location and relevant information of a person in distress, achieving the goal of remote monitoring and alarm. This research holds significance for the safety of waterborne workers and the control of maritime accident rates.
